8 Claims. 1

This invention relates in general to a reflector assembly for electriclighting fixtures and more particularly to an assembly in which a lampsocket may be conveniently and expeditiously connected with anelectrical outlet and the reflector may be readily mounted and locked inposition and, with equal facility, unlocked and demounted.

An object of this invention is to provide compact, safe, simple andeflicient means for quickly and securely mounting and locking areflector in position on a lighting fixture with provision for unlockingand detaching it with like facility.

A further object of the invention is to provide means in such anassembly for facilitating the connection of a lamp socket with anelectrical outlet and avoiding the exposure of loose conductors in suchan outlet preliminary to the connection, construction and arrangement ofparts illustrated in the accompanying drawings, and while there is showntherein a preferred embodiment of the invention, it is to be understoodthat the same are susceptible of modication and change without departingfrom the spirit ofthe invention.

The accompanying drawings illustrate a selected embodiment of theinvention, and the views therein are as follows:

Fig. 1 is a fragmentary side view, partially in section, of a lightinginstallation including a re-V4 ector assembly embodying the invention;

Fig. 2 is a detail sectional View of a portion of the invention shown inFig. 1, takenV along the line 2-2 of Fig. 4;

Fig. 3 is a detail view, partially in section, of another portion of thedevice shown in Fig. 1;

Fig. 4 is an inverted plan View of a portion of the invention shown inFig. 2;

Fig. 5 is a fragmentary plan View of a portion of the invention shown inFig. 1;

Fig. 6 is an enlarged detail sectional view along the line 6-6 of Fig.5;

Fig. 7 is an enlarged detail sectional view along the line l-l of Fig.5; and

Fig. 6 is an enlarged detail sectional view along the line 8-8 of Fig.6.

The particular assembly herein disclosed for the purpose of illustratingthe invention comprises a base or support Ill, generally hexagonal inform and having a central threaded opening I'I adapted to be threaded ona correspondingly threaded end of a conduit I2, Fig. 2. The support Illhas an annular flange l3 having a flat surface i4 adapted to receive agenerally annular plate I5 in abutting coaxial relation. The plate I5is`provided with openings I6 for receiving .screws `I1 which are seatedin corresponding threaded openings I8 in the said flange. The plate I5is also provided with spaced cut-away portions I9, Fig.- 4, arranged toreceive spaced bosses 20 provided on the support I0 and having threaded'openings therein for receiving screws 2|, Fig. 1, which are provided forsecuring to the support the lamp socket assembly '22, Figs. 1 and 3. Inorder to facilitate the connection of the lamp socket assembly with thesupport and an electrical outlet, enabling a. substantial saving of timein wiring over the usual practice, the lamp socket assembly 22 isprovided with spaced openings 23 for receiving the screws 2I` and isalso provided'with electrical connections in the form of spaced screws24 Fig. 3, and conventional cooperating vconductor parts for receivingthereonductors 25 carried by the conduit I2.

The plate l5 is provided with peripheral, angular ange portions 26, eachof which has a reverse angular flange portion 2l, Fig. 6, provided withan angulated edge 28, Figs. 6 and 8, in cluding an out-turned portion28a, Fig. 6, and a cut-away or recessed portion '29, Fig. 8, disposed inspaced relation with the periphery 30, Fig. 4, of the plate forlockingly receiving corresponding portions of a shade or reflector 3I,Fig. 1. The angulation of the edge 28 and the spacing of the angeportion 21, as shown in Fig. 8, are such Vas to provide a tapering latchreceiving space intermediate the edge and the adjacent surface of theannular portion of the plate.

The reflector 3| has a tubular end portion 32 adapted to receive thesocket 22. lThe inturned angular flange portion 33 is provided adjacentthe outer extremity of the tubular portion 32 of the reflector. Theflange portion 33 is provided with circumferentially spaced in-struckportions 34.

The'intermediate flange or latch portions 35 have angulated inturnededges 36 receivable Within the space intermediate the flange portions 26and `2l of the plate I5, and these edges 36 are Pros ceived in the saidspaces for relative rotation of the reflector and plate and when soreceived and upon such rotation the angulated edges oflthe' reflectorwill be received intermediate the angular flangei portions and thereverse angular flange portions of the said plate and the indentedportions will lockingly engage the cutaway portions of the plate tosecure the reflector in operative position in relation to the plate.

4. A reflector assembly comprising a support provided with an electricaloutlet, a lamp socket disconnectibly mounted on 'the support in elec-Vtrical lcommunication with the outlet, a reflector, and cooperativemeans on the reflector andsupport for releasably securing the reflectorto the support and in spaced relation with the socket comprising agenerally annular plate mounted on the support and having spacedperipheral angular flange portions, each flange portion including areverse flange portion arranged in angular spaced relation with the saidangular flange portion and having an angulated edge withv a cutawayportion therein disposed in spaced relation with the periphery of theplate, the reflector hav- Ving an annular end portion adapted to receivethe socket and provided with an inturned angular flange portion, theinturned flange portion having Icircumferentially spaced indentedportions and in-struck portions circumferentially spaced in relation tothe indented portions, the instruck portions being arranged to providespaces for receiving the angular flange portions of the plate, theportions of the inturned flange portion intermediate the in-struckportions having angulated edges, and the parts `being conformed andarranged to operate whereby the angular flange portions of the plate maybe received in the said spaces for relative rotation of the reflectorand plate and when so received and upon such rotation the angulatededges of the reflector will be received intermediate the angular flangeportions and the reverseangular flange portions of the plate and theindented portions will lockingly engage the lcut-away portions of theplate to secure the reflector in operative position in relation to thesupport, the said angulated edges of the angular flange portions of theplate being inclined toward the adjacent surface of the plate andarranged for frictional engagement with the said indented portions so asto limit relative n'ovement of the indented portions and the said e ges.
